P0732 2GR INCORRECT RATIO
DescriptionINFOID:0000000005397294
• This malfunction will not be detected while the OD OFF indicator lamp is indicating another self-diagnosismalfunction.
• This malfunction is detected when the A/T does not shif t into second gear position as instructed by the TCM.
This is not caused by electrical malfunction (circuit s open or shorted) but by mechanical malfunction such as
control valve sticking, improper solenoid valve operation, etc.
On Board Diagn osis LogicINFOID:0000000005397295
• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “P0732 2GR INCORRECT RATIO” with CONSULT-III is detected when A/T cannot
be shifted to the 2GR position even if electrical circuit is good.
• This diagnosis monitors actual gear position by checki ng the torque converter slip ratio calculated by TCM
as follows:
Torque converter slip ratio = A x C/B
A: Output shaft revolution signal from output speed sensor
B: Engine speed signal from ECM
C: Gear ratio determined as gear position which TCM supposes
If the actual gear position is higher than the position (2nd) supposed by TCM, the slip ratio will be more than
normal. In case the ratio exceeds the specif ied value, TCM judges this diagnosis malfunction.
This malfunction will be caused when shift solenoid valve B is stuck open.
• Gear positions supposed by TCM are as follows: In case of gear position with no malfunctions: 1, 2 , 3 and 4 positions
In case of gear position with shift solenoid valve B stuck open: 4, 3*, 3 and 4 positions to each gear position
above
*: “P0732 2GR INCORRECT RATIO” is detected.
Possible CauseINFOID:0000000005397296
• Shift solenoid valve B
• Each clutch
• Hydraulic control circuit
DTC Confirmation ProcedureINFOID:0000000005397297
CAUTION:
• Always drive vehicle at a safe speed.
• If performing this “DTC Confirmation Procedure” again, always turn ignition switch OFF and wait at
least 10 seconds before continuing.
After the repair, perform the following proc edure to confirm the malfunction is eliminated.

INPUT SPEED SENSOR A
DescriptionINFOID:0000000005397371
The input speed sensor detects forward clutch drum rpm (revolutions per minute). It is located on the input
side of the automatic transaxle. The output speed sensor is located on the output side of the automatic tran-
saxle. With the two sensors, input and output rpms are accurately detected. As a result, optimal shift timing
